In pediatric femoral shaft fractures, how does treatment vary with age?

• A. Younger children: traction and casting; older children: intramedullary nailing or rigid fixation.
• B. All require external fixation.
• C. Younger children: primary hip replacement.
• D. Older children: traction alone.

Answer: (A)

The main idea is that age determines how well a child’s femur can heal and remodel, guiding treatment strategies. Younger children have a strong remodeling potential and tolerate nonoperative management well, so traction followed by casting (often a hip spica) is commonly used to align and immobilize the fracture. In older children, healing is slower and remodeling is limited, making stable fixation important to maintain alignment and allow earlier function. Intramedullary nailing or other rigid fixation provides durable stabilization across the shaft, reducing the risk of malunion and shortening immobilization time.

This is why the best approach is to treat younger kids with traction and casting and older kids with intramedullary nailing or rigid fixation. External fixation isn’t the standard across the board, and primary hip replacement or traction alone in older children wouldn’t fit typical practice.
